so i checked my wallet a couple of days ago and noticed my 50 coins were missing.

i restored my wallet from a backup and after rescanning it showed i only have 0.05 coins left.

almost 50btc where 'sent' unauthorised from my wallet to 1LAosJwSQHmUzNnToPgjLaRTVUHP2WM8Wt

https://blockchain.info/address/1LAosJwSQHmUzNnToPgjLaRTVUHP2WM8Wt

according the my wallet it matches up on block chain showing 4 transactions. im still trying to follow it, but i have no idea what to do

i was trying to restore for backup and do a double spend, but it looks like its too late for that now...

it looks like they are trying to launder it, anyone else able to dissect anything out of this?
